The AirTAC GFR20008LF1WT AirTAC Filter Regulator NPT1/4, 5 um is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1/4" ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR20008LF1WT is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This size 200 unit takes a 1/4 in NPT thread, carries the finer 5 um filter element (code W, versus the standard 40 um grade), drains its polycarbonate bowl by differential pressure, and is built as the low-pressure regulator type with an embedded square gauge scaled in MPa. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
It is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, PT thread as standard and G (BSPP) or NPT to order, a choice of differential-pressure, automatic or manual draining, 40 um or 5 um filtration, and gauge or no-gauge builds. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |

| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Feeding clean, moisture-reduced and regulated air to the directional control valves on a form-fill-seal packaging line, with the 5 um element protecting spool clearances and the gauge giving the setter a direct pressure readout at the machine.
Conditioning the supply to grippers and small cylinders on an assembly-cell pick-and-place station, where the low-pressure regulator type lets the technician set a gentle downstream pressure for delicate handling and the bowl drains automatically as pressure falls.
Filtering and regulating shop air down to the low pressures atomising guns and air-assisted applicators need, with the 5 um grade keeping oil and water carry-over out of the finish and the square MPa gauge letting the painter verify the setpoint.
Size 200 with a 1/4 in NPT port suits circuits plumbed at 1/4 in; step up to 300, 400 or 600 when larger ports are needed. The 5 um element on this unit is the finer option - choose it when downstream equipment needs cleaner air than the standard 40 um grade. Draining is differential-pressure, which vents the bowl as inlet pressure falls; automatic and manual drains are available elsewhere in the family. The square MPa gauge is fitted, and external round gauges in MPa, psi or bar scales can be ordered, as can G (BSPP) thread in place of NPT. Flow is published as curves, not a single rating, so send us your flow and pressure requirements and we will confirm this unit's suitability against the datasheet before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm this unit's suitability from the datasheet before you order.
The L marks the low-pressure regulator variant: it regulates at lower downstream pressures than the standard GFR build. The exact adjustment range for this variant is not published in the standard tables, so ask us to confirm it against the datasheet for your setpoint. The rest of the code decodes normally: NPT1/4 port, 5 um element, differential-pressure drain and a fitted square gauge scaled in MPa.
